your outstanding article/ (*) has imparted a great/(*) idea for me. .
另外,對不熟的人如何使用祝福語?
normally at the end of letter, we provide some well-wishing words and expressions regularly for unfamiliar people who u want to contact, such as Best wishes, best regards, Good luck,/(*)Sincerely, etc...all depend upon what kind of letter you wrote.
希望有點用^^"
